Pololu QTR-MD-13A Reflectance Sensor Array: 13-Channel, 8mm Pitch, Analog Output
Detects changes with 13 sensors at 8mm pitch
Operates effectively from 2.9 V to 5 V
Optimizes performance at 5 mm sensing distance
Controls brightness independently of voltage
Detects objects up to 40 mm away
The Pololu QTR-MD-13A Reflectance Sensor Array: 13-Channel, 8mm Pitch, Analog Output is designed for precise detection of reflectance changes, such as line detection. It features an array of infrared LED and phototransistor pairs, operating effectively within a voltage range of 2.9 V to 5 V. The device allows for adjustable brightness control, independent of the supply voltage, with separate controls for odd and even emitters. It is capable of detecting high-reflectance objects up to approximately 40 mm away, with optimal performance at a sensing distance of 5 mm.
